Question

10. Two plots of land have the same perimeter. One is a square of side 64 m and the other is a
128 m. Find the area of the park.
rectangle of length 70 m. Find the breadth of the rectangular plot. Which plot has the
greater area and by how much?​

Answer 1

$\huge\boxed{\fcolorbox{black}{pink}{ANSWER}}$

Perimeter of square =4×side

=4×64=256cm

Perimeter of Rectangle = Perimeter of square

⇒2×(length+breadth)=256⇒2×(80+breadth)=256⇒breadth=48cm

Area of square =side×side

=64×64=4096cm²

Area of rectangle = = l×b

=80×48=3840cm²

Area of Square is greater than Area of Rectangle.

Answer 2

Answer:

Perimeter of square=4×Side

Perimeter of rectangle=Perimeter of square

2×(length+breadth)=256=2×(80+breadth)

Area of square=Side×Side

64×64=4096cm²

Area of rectangle=l×b

80×48=3840cm²

Area of square is greater than area of rectangle.
